Admit it, you've always wanted to blow up the Earth. Well, now you can "blow it up" -- that is, inflate it, with this wonderfully vivid Inflatable Earth Globe Beach Ball. Through a unique collaboration with NASA, thousands of satellite images taken from an orbiting array of satellites in 2003 are translated into an incredibly accurate image of planet Earth -- scaled down to 16" in diameter. The Earthball is not cluttered with political boundaries or city and country names. You don't see those from space! Cities around the world are depicted in photo-luminescent ink. Expose the ball to bright light for a couple minutes, then turn off the lights and the cities will glow in the dark! It's similar to how the Earth actually looks from space at night. Made of lightweight vinyl material, the Earthball comes with a 16-page booklet containing interesting facts, educational games, and resources for further exploration. So go ahead, blow it up!
